SPARK-INTENSIFIER FOR SPARK PLUGS.

Specification ofLetters Patent.

Patented M ii, rail 6.

' Application filed October 16, 1914:. Serial No. 866,969.;

T 0 all whom it may concern Be it known that I, GEORGE RICHARD MEIssNnn, a citizen of the United States of America, residing at Albia, in the county of Monroe and State of Iowa, have invented certain new and useful Improvements in Spark-Intensifiers for Spa1'k-1lugs,of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in spark intensifiers to increase or decrease the spark gap; meansbeing provided on pne of the electrodes for connecting one of the circuit wires; the other electrode having a flattened head to allow the same to be connected to one of .the electrodes of the spark plug.

I am aware that spark intensifiers have been made in which a tube of insulating material formed a support for the electrodes; said tube having "a" transverse bore in order to enable the spark gap to be seen. However, in installing this form of spark intensifier in connection with an ignition system'in an automobile, it very often happens that the spark gap cannot be seen.

With my improved construction, a pair of insulating disks are employed for supporting the electrodes and said disks are spaced and inclosed in aglass casing which allows the spark plug to be seen from any angle at the same time, a construction of spark in tensifier is formed which is exceedingly strong and durable and which can be readily assembled and taken apart.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel 'features"thereof defined by the appended claims.

In the drawings, Figure 1, isa perspective of my improved construction of spark intensifier; and Fig. 2,

is a longitudinal section through the same.

formed of gobd insulating material which Like numerals of reference refer to like parts in the several figures. of the drawings. In carrying out my invention, I employ a pair of circular disks. 1 and 2 preferably are-provided with oppositely disposed socketsin their opposing faces in which are mounted spacing'plugs 4 secured in position therein by screws 3 passing through the disks into bores formed in the ends of the plugs 1 so as to form a,rigid connection whereby the disks will be held properly spaced in such a manner that all danger of sparks jumping to the spacing plugs, is prevented, and a construction'is provided which is exceedingly simple and cheap to manufacture.

'Arranged over the outer faces of the disks v:

1 and 2 are mica sheets 5 held in position thereonby-metal caps 6 and 7 having cen-I tral openings registering with openings formed in the mica sheets and threaded bores 8 formed in the disks 1 and 2 in which are mounted screw electrodes 9 and 10 having reduced ends 11, and it will be seen by other in order to increase or de'creasethe spark gap.

The screw electrode 10 is provided'with a flattened head 12 adapted to be connectedto the electrode of the spark plug; said head forming means for turning the screw within" its threaded bore by adjusting the position of the same. lhe screw electrode 9 is pro- .vided with a slotted end 13 to receive a and it will be noticed that the head 12 of 100 the opposing electrode, answers the same purpose. p v

The insulating disks and electrodes are encased by a blue glass tube 16 arranged within the flanges of the caps 6 and 7 which are 105 insulated as clearly shown. It will be seen that by incasing the electrodes-in a blue glass tube, the spark is made visible from any angle.

From the foregoing description, it will be 11a so this construction that these reduced ends. or points can be adJusted in respect to each seen that I have provided a spark intensifier for spark plugs in which the electrodes are adjustably mounted in respect to each other in order to increase o'r'decrease the spark gap; said electrodes being mounted. Within a glass tube in order to allow the spark gap to be readily seen from any angle.

I claim:

l. A spark intensifier, comprising a pair of insulating disks, plugs for spacing said "disks, electrodes adjustably mounted within ranged on saiddisks, a glass tube arranged between said caps, and electrodes mounted within said threadedbores of said disks for holding said caps in position upon said insulating disks.

3. A spark intensifier, comprising a pair 'of insulating disks, electrodes adjustably.

mounted within said disks, means for holdmg said disks spaced apart, caps surrounding said disks and held in position thereon by said electrodes, and a glass tube arranged between said caps surrounding said disks.

. l. As a new article of manufacture, a spark intensifiercomprising a pair of 013- posed insulating disks, spacing plugs con-- necting said disks, means for securing said plugs to said disks, mica sheets arranged upon said disks, caps arranged upon said mica sheets, a glass tube arranged between said caps, and electrodes adjustably mounted within said disks for securing said caps in position upon said disks.

5. A spark intensifier, comprising a pair spaced insulating disks provided with vtrally arranged threaded bores centrally threaded bores, apertured sheets of mica arranged upon the outer faces of said disks, apertured caps mounted upon said sheets of mica, a glass tube arranged between said caps and surrounding said insulating disks, and threaded electrodes mounted within the threaded bores of said insulating disks having means for clamping said caps in engagement with the ends of said tube.

6. A spark intensifier, comprising a pair of insulating disks having electrodes adjust-' ably mounted therein, spacing members disposed between said disks, eaps carried by said disks and secured thereon by said elec trodes and a glass tube arranged within said caps surrounding said disks and electrodes.

7. A spark plug intensifier, comprising a pair of insulating disks, spacing plugs connecting said disks, caps provided with marginal flanges mounted upon said disks, a

glass tube arranged between saidcaps engaged by the flanges thereof, and electrodes mounted within said insulating disks hav-, ing means for engaging said caps for clamping said tube between said caps.

8. Aspark plug intensifier, comprising a pair of insulating disks providedi with cen- 'and oppositely disposed sockets upon their opposite faces, plugs having their ends-seated in said sockets, screwspassing through said disks into said plugs, caps provided with marginal flanges mounted upon said disks, a

glass tube arranged between said caps and embracing said disks, and electrodes mount ed within said insulating disks having means for engaging said caps.

In testimony whereof I hereunto affix my signaturein the presence of two Witnesses. GEORGE RICHARD MEISSNER. Witnesses: FRED C. HUEBNER, MAX AUSELANG.
